Transmission Breather
Checking
Transmission housing breathers (if equipped) must
remain clear. A plugged breather could result in
pressure build-up, which could cause oil leakage.
If the breather is plugged, clean or replace it. See
Fig. 5. Check more often if the vehicle is operating
under very dusty conditions.
